California Sea Lion Pup Crisis: Understanding the Causes and Consequences

The California sea lion pup crisis is a pressing issue that affects not only these adorable creatures but also the ecosystem as a whole.

California sea lion pups are struggling to survive due to a lack of food.

This is largely attributed to the collapse of their primary food source, the sardine fishery, which was once a staple in their diet.

In 2015, the sardine population dropped dramatically, leaving sea lions with limited options.

Pupping season starts early, with the first California sea lion pup arriving on December 1, 2015, at The Marine Mammal Center. This pup, named Chilly, was just five months old and in desperate need of nutrition and fluids.

Typically, a California sea lion of this age would still be with its mother on the Channel Islands, where thousands of mother sea lions give birth and nurse their pups for 10-11 months.

In a normal year, pupping season wouldn't start until March, when newly weaned elephant seal and harbor seal pups begin to show up. But last year was different, and we saw a surge in California sea lion pups in December and January.

By the end of January, we had responded to 102 sea lions, and things only got worse from there.

If you see a stranded sea lion, don't approach or attempt to aid it, contact our local stranding network or local lifeguards or harbor police.

SeaWorld responds to live animal calls at 800-541-7325, and you can report a dead animal to the NMFS Southwest Fisheries Science Center at 858-546-7162.

The National Marine Mammal Foundation is helping rehabilitate the pups, and donations to their Emergency Fund will go directly to fund sea lion care and medical support.

Typically, this time of year, the Marine Mammal Center might have about a dozen patients in their care, but right now, they're responding to about a dozen animals a day.

These sea lion pups must be individually tube-fed a special formula of ground-up fish, water, and salmon oil multiple times a day because they don't yet know how to eat fish.

In January, the Marine Mammal Center successfully rehabilitated and released some of these animals, including Chilly, Cupid, Navidad, and Partridge.

Pups begin to group together at two to three weeks of age.

California sea lion pups develop vocal, social, and swimming skills by interacting with others in these groups.

These social groups break up by the end of the breeding season when the adults leave the rookery.

Research suggests that mothers and juveniles recognize each other after weaning and may continue to associate with each other.

California sea lion pups learn by mimicking adult behavior, which is an essential part of their growth and development.

Here are some key milestones in a California sea lion pup's development:

We're in the middle of a California sea lion crisis right now. The Marine Mammal Center is responding to about a dozen animals a day, which is a significant increase from the typical dozen patients they usually have in their care this time of year.

The crisis is particularly affecting young sea lion pups, who are stranding in a near-death state. These pups must be individually tube-fed a special formula of ground-up fish, water, and salmon oil multiple times a day.

More than 1,000 baby sea lions have been stranded in Southern California since the first of the year, which is a staggering increase from the normal number of less than 100. This has prompted the National Oceanic and Atmospheric Administration (NOAA) to declare an Unusual Mortality Event for California sea lions.

The increase in sea lions washing up on local beaches intensified over the Easter weekend and scientists have expressed serious concern since the traditional peak stranding season is just now beginning. Researchers have observed underweight pups on the breeding rookeries, a sign that typically occurs in association with food shortage.

If you see a stranded seal or sea lion, please do not approach or attempt to aid it. Contact your local stranding network, lifeguards, or harbor police for assistance. For live animals, you can call SeaWorld at 800-541-7325, and for dead animals, call the NMFS Southwest Fisheries Science Center at 858-546-7162.

Donations to the NMMF Emergency Fund will go directly to fund sea lion care and medical support, so consider contributing to help these vulnerable animals.

We're doing everything we can to learn more about what's causing these strandings. The Marine Mammal Center has 40 years of experience rehabilitating California sea lions, and this is an unusually unusual occurrence.

These young sea lions are stranding at an early age and in poor condition, which is especially concerning. California sea lions are considered sentinels of the sea, so their struggles are often an indication that something complex is happening in the ocean environment.

We're performing detailed exams on patients and necropsies on animals that don't make it. This will help us understand what's causing these strandings and how to prevent them in the future.

The National Marine Mammal Laboratory is working closely with us to monitor the mother-pup pairs at the rookeries on the Channel Islands. They believe the mother sea lions may be having trouble finding enough food to support their nursing pups.
